Froth flotation is a widely used separation process throughout the mineral processing industries in the last century because of its ability to treat complex and low grade ores, where the mineral particle size is too small for other separation techniques to be efficient. It can be a highly efficient process for

Jan 13, 2012· "It is important to emphasise the interlock between grinding and flotation, not only with respect to particle size effects, but equally to flotation feed rate variations. The grinding circuit is usually designed to produce the optimum size distribution established in testing and given in the design criteria.

The flotation and flocculation behaviors were further analyzed by Xray diffraction analysis, zeta potential measurements, particle size distribution and other methods. The successful separation of rare earth minerals by flotation was attributed to the selective adsorption of the collector onto quartz, making it particularly recoverable by reverse flotation so as to be separated from the valuable materials.

The flotation behaviour of fine particles was also studied in a previous work by this Australian group [16]. It was indicated that the minimum critical contact angle increased in value as particle size decreased, for flotation to be initiated. As a consequence, a nonfloating component exists within a .
